In a move that should surprise nobody, Apple has sort-of admitted to iPhone antenna problems in their press conference this morning, claiming it affects a small number of users, but they claim to be working hard to fix the problems that they have confirmed. They've offered free bumpers (that have until now been a $30 accessory) to all iPhone buyers, and are offering to waive any restocking fees for anyone who wants to return their iPhone 4. Whether or not there's going to be a hardware fix for future iPhones, Steve Jobs says he doesn't know yet whether that will happen.
